Title: Improvements in or relating to waveguide coupling units
Inventor: DAVIDSON CYRIL FRANK
IPC: H01P5/08
Filed: 1962-10-08
Abstract: 1,005,840. Waveguide Junctions. POST MASTER GENERAL. Jan. 7, 1964 [Oct. 8, 1962], No. 38059/62. Heading H1W. A microwave coupling device comprises a coaxial waveguide coupled to a rectangular or circular waveguide by a member of coupling guides and a further waveguide coupled to the interior of the coaxial guide. The TR coupling device shown in Fig. 1 comprises a co-axial guide 2, 3 for propagation of transmitted energy in a circularly-polarized TE 11  coaxial mode. The ports A, B are connected to an aerial feeder. The coaxial guide is linked by four symmetrically disposed rectangular guides 11 and posts 6, 9 to a circular feeder guide 7 which is fed with circularly-polarized energy from a turnstile junction 12. Energy is received at a frequency greater than the transmitting frequency and is propagated in a circularlypolarized mode along the inner conductor 2 of the co-axial waveguide. Here it is converted to a plane-polarized mode by e.g. a quarterwave phase-shifter 13 and coupled into a rectangular feeder guide 14. In a modification (Fig. 3), the transmitted and received waves are plane-polarized and are fed in a TE 11  mode respectively along the co-axial waveguide 30 and along the inside of the inner conductor 31. The coaxial guide is transformed from a circular to a rectangular section and coupled to a power-splitter 35 having rectangular branches 45, 46 which are reunited at junction 40 and coupled to a rectangular feeder 38. The received energy is fed from the inside of the coaxial guide to a right-angle bend 47. The device may be modified for the transmission and reception of circularly polarized waves by the addition of suitable polarizers.

Title: A method of producing consumer gases resembling natural gas
IPC: C10G47/00
Filed: 1964-09-18
Abstract: A combustible gas resembling natural gas is made by mixing a liquid hydrocarbon or liquefied normally gaseous hydrocarbon, e.g. butane, with steam, with a town, refinery or similar H2-rich, CH4-poor gas, and reacting the mixture over a catalyst under slightly exo- or endothermic conditions to produce a gas of high c.v. than the original gas.  The final gas may be converted and have its CO2 content reduced conventionally. The catalyst may contain Ni, Co, Mo, W, or Re, on a magnesia or alumina carrier and may be activated by alkali or alkali earth metal compounds, and the temperature is in the range 400 DEG  to 700 DEG  C., preferably 450 DEG  to 550 DEG  C. The pressure may be normal, or up to 50 atmos., and the reaction is almost autothermic, the thermal balance being +50 Kcal per cubic metre (S.T.P.) of gas produced. Two specific examples are described. In one, butane and steam are reacted with coke oven gas; in the other, light petrol (B.P. up to 120 DEG  C.) is reacted with steam and with the same coke oven gas. The compositions of the coke oven gas, of the dried crude gas, and of the make gas after washing out most of the CO2, are given.  The final gases are rich in CH4 (i.e. 72% to 80% by vol.).  The final gas may preheat the gasification medium and vaporize the hydrocarbon.

Title: Improvements in or relating to tunnel diode circuits
Inventor: THOMPSON PHILIP MARTIN
IPC: H03K17/58
Filed: 1960-11-11
Abstract: 1,009,203. Tunnel-diode switching circuits. PLESSEY CO. Ltd. Jan. 10, 1962 [Nov. 11 1960], No. 38751/60. Heading H3T. In a circuit, Fig. 4, comprising two tunnel diodes E 1 , E 2 , both of which are so biased by respective current sources M 1 , M 2  that they may each assume either of two stable states, the tunnel diodes are coupled together by a conventional rectifier diode D, the circuit being so disposed that the three diodes are connected together in series with the same polarity and means being so provided and the circuit being so biased that one tunnel diode (e.g. Eg) may be changed from its low-voltage to its high-voltage state when the other tunnel diode (e.g. E 1 ) is in its low-voltage state but not otherwise. In the circuit illustrated the biasing currents supplied by sources M 1 , M 2  are such that less additional current is needed to bring diode E 2  to the peak on its characteristic curve that is needed in the case of diode E 1 . Then, assuming diode E 2  is initially in its low-voltage state, on the application of voltage pulses of amplitudes one-quarter volt positive and negative to terminals B and A respectively, current will flow through diodes E 2 , D and E 1  in series provided diode E 1  is also in its low-voltage state and diode E 2  will be switched to its high-voltage state. However, if diode E 1  is initially in its high-voltage state, the one-half volt established across the series circuit will be insufficient to cause substantial conduction in diode D and diode E 2  will remain in its low-voltage state. In the application of the circuit shown in Fig. 6, the state of tunnel diode E 1  can be made to control, in turn, the states of tunnel diodes E 2 , E 3 , E 4  and so on. Initially, the magnitude of the negative voltage applied to conductor L 2  is made greater than that of the positive voltage applied to L 1 ; hence on applying quarter-volt pulses of appropriate polarity to terminals A and B, diode E 2  can be made to assume the opposite state from that of diode E 1 . Then subsequently the voltage at L 1  is given the greater magnitude (so as to ensure that the information continues to travel from left to right) and pulses applied to terminals B and C, diode E 3  thereupon taking up the state originally held by diode E 1 . In a further circuit, Fig. 7, each of several diodes E 2 , E 3  &c. can be made to assume the converse of the state of diode E 1  by applying pulses to terminals B, C, D and E in turn. In the circuit of Fig. 8, diode E 3  is switched to its high voltage state if either E 1  or E 2  is in its low-voltage state. The circuit may be modified, Fig. 10 (not shown), to include further tunnel diodes so that the output diode is switched to its high-voltage state if any one of the other diodes is in its low-voltage state. In an alternative circuit, Fig. 9, is either diode E 1  or E 2  is set to its high-voltage state, diode E 3  also becomes set to its high-voltage state.

Injury to the operator or to the machine caused by the presence of an obstruction, such as the operator's hand, under the impression device is thus avoided. The machine shown is an addressing-machine of the type com. prising an impression roller 6, which is mounted in a carriage 7 slidable in guides 8 on a rocking platen arm 5, and, when the arm is lowered, is rolled over address-plates 3 fed in succession along a guideway 2 in the machine bed 1.
